Get Miner Reserves
GET/v1/cryptodata/on-chain/miners/reserves
BTC miner pool reserves + 24h/7d/30d net flow per pool. Tracks reward addresses for Foundry USA, AntPool, F2Pool, ViaBTC, and Binance Pool. Most pools sweep balances immediately (low standing balance is normal); the meaningful signal is the cumulative funded/spent delta over rolling windows. Net flow interpretation: - **Negative net** (heavy spending): miners selling — bearish pressure - **Positive net** (accumulation): miners holding — historically late-bear - Windows show as `available: false` until enough snapshots have accrued
